The legendary Fat Boy is the symbol of the modern American cruiser: a motorcycle that combines distinctive style and solid performance, capable of tackling long roads with stability and safety. When original brakes begin to show signs of wear after thousands of miles, it's time to rely on a solution that doesn't compromise the quality and aesthetics of this icon.
Brembo offers the Brembo Serie Oro Brake Disc Kit for the Fat Boy 1340 (89-99) with two complete solutions: the 78B40822 for the front and the 68B407E0 for the rear, both with 292mm diameter and 5mm thickness. These discs maintain original specifications while offering superior braking efficiency, thanks to Brembo technology proven on thousands of motorcycles worldwide.
The aluminium bell reduces unsprung weight and improves suspension reactivity, while the strategic drilling ensures instant heat and friction gas evacuation. The result is more consistent braking response, especially in curves and repeated braking on long rides. Pad attachment is optimized for precise modulation, a fundamental element on the Fat Boy where speed control must be fluid and predictable.
These discs are TÜV/ABE certified and represent the direct OEM replacement without any revision required. Installation is completely drop-in: no modifications, no adaptations, pure simplicity. Certified 100% Made in Italy, they guarantee 2 years of full coverage and the peace of mind of a brand that has equipped the most prestigious motorcycles for decades.
